摘要：

Wind-induced vibrations of two actual tall towers were reduced to about half upon installation of newly developed Tuned Sloshing Damper, which utilizes liquid motion in circular container. Vibrations at Nagasaki Airport Tower (height 42 m) and Yokohama Marine Tower (height 101 m) were measured during gusty day, before and after installation of damper. The reduced vibration levels after installation were in the range acceptable from the view point of comfort and serviceability. To further estimate the effects of Tuned Sloshing Damper, the dynamic force frequency response function of STD was experimentally determined. Using this frequency response function, numerical simulation on gust responses was conducted. The results indicate that the amplitude level is reduced to about half and this qualitatively agrees well with observation in the Yokohama Marine Tower. © 1990.
